This manual provides installation and operation instructions for the heat pumps .Read these

installation and operation instructions carefully before proceeding with the installation.

Consult the local distributor with any questions regarding this equipment .Please read this

manual carefully before you install. Start, repair or maintain the unit. Installation and service

must be performend by a qualified installer.The manufaturer shall not be responsible for any

damage of the unit or physical injury or death caused by improper installation,debugging,

operation,maintenance or disregarding the manual.

1.2 Consumer Information and Safetyo oa.We recommend 80 F (27 C)as the optimun water temperature for swimming. Overheated water

may cause tiredness and reduce comfort of swimming.b. The drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness, and subsequently result in drowning.c. Pregnant women take note! Soaking in water above 102 (38.5 ) can cause fetal damage during the fi rst three months of pregnancy (which could result in the birth of a brain-damaged or deformed child). If pregnant women are going to use a spa or hot tub, they should make sure

o o the water temperature is below 100 F (38 C) maximum.d. The water temperature should always be checked with an accurate thermometer before entering aspa or hot tub. e. Persons with a medical history of heart disease, diabetes, circulatory or blood pressure problems should consult their physician before using a hot tub or spa.f. Persons taking any medication which induces drowsiness (e.g., tranquilizers, antihistamines, or anticoagulants) should not use spas or hot tubs.g. Prolonged immersion in hot water can induce hyperthermia.

1.3 Energy Saving Tips

It is important to note that a heat pump will not heat a pool as fast as a large gas or electric pool heater. If the pool water is allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it is more economical to maintain the pool water temperature at or near your desired swimming temperature. If you do not plan to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the temperature setting of the control several degrees to minimize energy consumption.

o o o o oa.Use an accurate pool thermometer. A difference of 4 F(2 C) , between 78 F and 82 F (26 C

o and 28 C), will significantly increase energy consumption. b. Carefully monitor the water temperature of your pool in the summer time. You can reduce heat pump usage due to warmer air temperatures.c. During the winter or when on vacation for longer than a week, turn off the heat pump.d. Find the proper setting on the heat pump temperature control e. Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or fencing.f. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool cover will reduce heat loss.

5.1 MaintenanceGeneral Maintenance:

a.The unit should be maintained twice a year by qualified technicians. If the

unit is located in coastal area, more frequent maintence is necessary.

b.A professional technician should clean the unit periodically. Tt is NOT

recommended to use a sprinkler to flush the unit.

5.2Troubleshooting

5. Maintenance and Trouble shooting

c.The unit is designed to withstand only normal rainfall.A flow of water entered into

the internal of the unit may damage the components. If the unit is located under the

eaves, span a water guide to prevent water flow falling into the unit.

4.Clean the drain hose.

Keep proper water flow:

a.Keep the filter clean. The filter may get dirty along with using.Adirty filter can re

duce the water flow .

b. Keep the pump clean, too.

c.Check the valves often.

The unit would not run:

a.Is the screen of control panel lit? If ont, make sure the electrical wires and cables

are correctly connected and the power is on.

b. If the screen displays“E7”,check the water flow. Whether the water pump is

running normally or the filter is jammed?

c.The unit will stop running automatically when the pool water reaches the set

temperature

The unit is running but not heating:

a. Is the air discharged from the fan cooler than the ambient temperature?If not,

ask a professional technician to check the refrigerant system.

b.Be sure the space around the unit is broad enough.There should not be obstru-

ction of air.

c.The unit will defrost when the ambient temperature is lower than normal con-

dition (usually when the temperature is lower than8 .

Installation

3.1 General information

3.0 Installation

Inspect the casing,unit and spare parts after receipt for possible for

possible damage in transportation. Check whether there is breakage of

the casing and cabinet, deformation of the unit,shed parts.The

manufacturer shall not be responsible for any damage due to improper

hanging or shipping.

Install the heat pumps in accordance with the procedures in this manual,

lacal codes and ordinances.

Correct installation is required to assure safe operation.The requirements

for heat pumps include the following:

a.Appropriate site location and clearances.

b.Sufficient air ventilation.

c.Proper electrical wiring.

d.Adequate water flow.

This manual provides the information needed to meet these requirements .

Review all application and installation procedures completely before

continuing the installation.

3.2 Location

The unit should be usually installed outdoor (NOTE: Indoor installations

require special considerations for condensate drainage and venting the

cold air produced by the heat pump.)

Install the unit downstream of all pumps and filters and upstream of all

chlorinators,ozonizers and chemical pumps.

Keep lawn sprinkler heads from spraying on the heat pump to prevent

corrosion and damage .Use a deflector if needed.

Make sure the heat pump is not located where large amounts of water may

run-off from a roof into the unit. Sharp sloping roofs without gutters will

allow massive amounts of rain water ,mixed with debris from the roof to be

forced through the unit. A gutter or down spout may be needed to protect

the heat pump.

3.4 Drainage

While the unit is running water in the air may condense on the fins of

the evaporator.If the air humidity is very high,the condensatin water

within an hour can be several gallons. The water will flow down to the

base plate through the fins. The factory provide optional drip tray to

collect the condensation water. Please couple it with a hose to dain

the water to a suitable place.

3.5 Electric wiring

General Requirements:

Read the information of the manual befor connecting .It is

compulsively required that the cables should be wired

by a qualified electrical technician. Connection made by

be unprofessional people may cause electric shock even death.

The manufacturer shall not be responsible for the consequences

of connection made by unqualified people or disregarding the

manual.

a. No power supplied to the unit while connecting.

b. Always comply with the national and local electrical codes

and standards.

c. In case any emergency occurs, the unit must be equipped

with a breaker.

3.6 Initial startup

Start the unit after finishing connecting for comprehensive examine

and debugging.

With any new pool or spa installation,operate the filter pump with the

heat pump off long enough to completely clean the water.This will

remove any installation residue from the water.

Notice : the unit will not heat the pool when the water pump is not

working.

Starting Steps:

a. Check whether the connections, wires and cables of the unit, water

pump, chlornator, ozonizer, chemical pumps and control panel are

corrctly coupled or connected .

b. Turn on the water pump and filter.Check for water leakage and verify

the water flow.

c. Turn on the power of the unit.Then press the button ON/OFFon the

control panel. The unit will start in several seconds.

d. After the unit runs for a few minutes, check whether the air discharged

from the fan is cooler than the ambient air.

e. Turn the water pump off while the unit is running. The unit should stop

working automatically. If not, adjust the flow switch.

f. Turn on the unit again, set the temperature on the cpntrol panel and

keep the whole pool system running. The unit will stop running

automatically as the pool water reaches set temperature plus 1degree.

When the temperature drops to 1℃ lower than the set temperature,The

unit will restart automatically.
